T0 all whom it may concern: I

Be it known that I, AARON P. GooLo,.a citizen of the United States, residing at Northwilkesboro, in the county of Wilkes and State of North Carolina,'have invented a new and useful Mechanical Movement for Agitating Bolters and Grain-Spouts, of which the. following .is a specification.

V The subject of this invention is a mechanism for agitating the bolter and grain spout of a mill wherein a cam groove engaging element is pivotally secured to an agitating lever and arm; and the objects of the invention are, first, to provide a collar adapted to engage a cam groove, second, to provide means for pivotally securing the collar toan agitating arm and lever, third, i to provide a novel, detachable connection which will not Wear loose and rattle, fourth,

to provide a simple and efiicientmechanism for the purpose set forth.

With the foregoing and, other objects in view' which will appearas the description proceeds, the invention resides in the com bination and arrangement of parts and lI1 the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed,'witl1- out departing from the spirit of the inven-, tion. V V

Practical embodiments of the invention are shownin-the accompanying drawings,

wherein z- ,7 Figure 1 is a perspective view of a mill i with an agitating mechanism constructed in accordance with my invention in place a V 7 shaft 14: and the sleeve is formed with a. cam groove to which is adapted a collar plate 17.

thereon.

Fig. 2 is .a perspective view of a portion of a mill and showing a modified form of the agitating mechanism.

Fig. 3 is a similar view showing another modification.

Fig. 4 is a detail plan view of the mechanism, the grain spout agitator. being cut away. 1

Fig. 5 is a detail side elevation partly in section of the detachable connection for the bolter agitator.

Fig. 6 is a detail side elevation of the collar. the cam shaft shown in section.

' Referring to the drawings by numerals As the mill to which the mechanism is at? tached forms no part of the -present invention, only sufiicient description be' given Specificationof Letters Ifatent. Patented Application filed May 31, 1917. Serial No. 171,991. 7

thereof to convey a clear understandingof the connection andoperation of the mechanism forming the subject of the present invention.

A supporting base, indicated generally Mar. 19', 1918.

1, is provided, and upon this base is sev cureda casing 2, which forms a housing for the burs of the mill and within which they turn. Ah'opper 3 is supportedupon legs 4 4, above-the casing 2. .The. hopper 3 has a depending'discharge spout,-the feed from which is controlled by a sleeve-5, carried on .one end of a lever 6, which is fulcrumed on an arm? rising from the casing 2. The lever isxactuated to regulate. the feed by a hand nut 8 which is threaded on a rod which rises from the casing. 2, and

the lever is held in contact with the nut by a coiled spring 9, which-surrounds thelrod and is confined between the lever and the top 'ofnthe casing 2. The hopper discharges into a grain spout, indicated at 10, andfrom this spout the cleaned. and separated grain is fed to the ,bursby a ;feed spout, not

shown. 1 A: discharge spoutl'l leads from the casing 2 and conveys the ground meal from base and to this shaft the runnerbur is secured and upon this shaft the drive pulley 14' is mounted. The thrust wheelandjam nut, indicated 7 generally at 15, e are provided for the purpose of regulating the spacing of theburs and controlling the grade of the ground meal. I e 1 A cam sleeve 16 is mounted on the drive The collar 17 is formed ,with iournaling means here shown as a hub 18 and-a hub 19 proiecting radiallv from its periphery. .A stub shaft 20 oscillates in the hub 18. and

the ears21 formed at one end of a block 22-which is secured to the end of a bent agitator arm 23. The arm 23, is pivotallvsecured to a bracket 24' which extends from one side of the casing 2, and supports. on its other end. the rain spout 10. A similar stub shaft 25 oscillates in the hub 19 and is pivotally secured to one end of a lever 26. The lever 26 isradiustabllv fulcrumed by a pin 27 on a bar 28 whichjforms part of a frame which is secured to the base. The

this stubshaft is pivotally hung between V other end of the lever 26 has a sulostantially conical stud 2 8 rising from it. A re silient finger "29* "is-pivoted to the lever 26* and overlies thestud. This endtof the lever 26 is adaptedto be detachably pivoted'to the handle of thebolter 12; This handleis provided-"With an"inserted conical "cap 30 forming a socket adapted? to. receive the:

stud 28 and to be detachably retained in place thereon bythe 'resilient finger: 29.

' securedito =a' crank 1arm:- 32 'which extends from a median point-ofa :rock shaft 33.

The rock shaft 33 :is verticallyidisposed and has-itslovver: end: stepped in a bracket 34 which is secured tothebase of the mill. The upperzend 'of the-shaft 33} is supported by a brac1 et 35 whidh* is secured to the casing, 21 Acrank ti; provided with a series ofapertures- 37} extends 1 from" the:-upper end of the rock shaft 38 and is adj ustably 'pivoted by apin 38 totheagitator arm 23 of the grain spout.- Another crank 39 extends from the lower "portion -02? the rock shaft 33 'and its pin: 40 is engaged bfy the -biturcatedifend fltl o the-'bolter'a itating-lever 26 Imtl'msmodi cation shown ing Fig. 3, the parts are the same i as ust described with the exception 0t i'th'e crank: '39 which is -10- catedf somewhat higherqup 'theshaft than the 'crank 39lwas Sand 'at; .Mhi'to the position occupied bythe cranlr '39l A1ink 42 is "piv otally; secured atfone' end 'tofthecrank 39? and its other end pivotally engages an a rm bolter handle In" this instance the bolter is provided ivvi-thfla trunnionit which turns in a; suitably supp orted' bearing "45. This gives 4 the bolter a. rocking instead tot its usual reciprocating motion. p I

In practice; the invention operates in the follbwing manner z Rfi'erring' particularly toeF-igi" 1 shaft revolves; the collar 1T= Will"b.'e movedso as to reciproc'ate the hhlo "18 tovv-ard' and away from' the ='casing' 2. This arocksnthe. arm-"23. upon its pivot and causesan agitation offthegrain spout. At the esame: time 7 the hub 19 has been I moved back? andforth a. horizontal plane,roc1

ing the lever 26 on its pin 27 and reciprocating the bolter 12.

\ Vhen the modification shown in Fig 2 e is used thecmoveinenttof .the hubc18, just described; will cause the shaft 33 to be rocked. This will reciprocate, through. the crank 36and arm 23, the grain spout; Motion will vals'oib'e imparted through the crank 39 and lever 26 to the bolter.

With the modificationvsh'owlrin Fig,- 3, the'same aotiontakes place With -the eXception that it-he: link; 4-2-13 reciprocated by the crank 39 and rocks thevboltei" upon its trunnion 44; v

By making the fol'li 'llrihe' formota plate, a"=langer bearing surface isprovided which avoids rapid Wear a and prevents loosening and rattl-ing of the-parts; The spring pressed conical connection'betwee'n the lever and bolter handle alsocompensates foravear and prevents the: parts b'ecomingloose and working to form the openingginto a; slot-.
